Self-Assembled Epitaxial Nanocomposite BaTiO₃−NiFe₂O₄ Films Prepared by Polymer-Assisted Deposition

Abstract

We present a new approach, cost-effective polymer-assisted deposition, to prepare self-assembled epitaxial BaTiO 3 −NiFe 2 O 4 nanocomposite films on LaAlO 3 substrates. Ferroelectric BaTiO 3 is embedded in the ferrimagnetic spinel NiFe 2 O 4 matrix. The composite shows both ferroelectric and ferrimagnetic properties.
